Re: bug report: dates on diff

If you didn't create this repository back in 2012, then the syntax
"master@{01-01-2012}" that asks "Back at the beginning of 2012, what
object did the master branch point at?" does not have a sensible
answer.  That can be seen in the warning you got from Git.

Hope this clarifies.

Thanks; it does explain what I saw, and even makes some sense.

However, it does leave me scratching my head about how to accomplish what I set
out to do, or just how to reference commits by their dates as displayed by git
log w/o either changing the system time/date when committing historic data
(which seems like a total no-no), or making multiple passes over "get log" to
determine how to ref. Perhaps there's a way to patch the log to match dates
recorded in relevant objects?

Trying not to sound snide, but, what's the point of "--date=" on commits if you
can't use it later? Granted, things always seem harder until you understand how
the work. Thanks again.
